Abstract

The invention relates to an inductive ignition system, in particular for infantry weapons, having a primary coil (2) which cooperates inductively with a secondary coil (3) in the ignition system of cartridge (4) and which transmits the firing energy that is required for the ignition. For the necessary firing energy to be produced and made available internally, that is with additional supply, the invention proposes fitting a weapon breechblock component (5), displaceable from a cocked position to a firing position, in the weapon housing (1) in which is located the primary coil (2), and that, for production of the ignition energy, an inductive power generator (6) is provided whose coil system (7) is fitted in the weapon breechblock component (5) and whose magnet system (8) is fitted in the weapon housing (1). On displacing the weapon breechblock component (5) from the cocked position to the firing position, the coil system slides pass the magnet system (8) and induces the necessary ignition energy in the coil system (7).

Description

Die Erfindung betrifft ein induktives Zündsystem, insbesondere für Infanteriewaffen.The invention relates to an inductive ignition system, in particular for infantry weapons.

Die induktive Anzündung wird vorzugsweise eingesetzt für Maschinenwaffen im Mittelkaliberbereich. Hierzu ist im Waffengehäuse eine Primärspule angeordnet, die induktiv mit einer Sekundärspule im Anzündsystem der Patrone zusammenwirkt und die zur Anzündung erforderliche Zündenergie überträgt. Die Zündenergie wird durch eine externe Versorgung (Batterie, Bordnetz, etc.) bereitgestellt. Hierzu müssen Kabel verlegt werden. In der DE 32 31 369 C1 ist eine beispielhafte Sekundärspule für die Patrone beschrieben.Inductive ignition is preferably used for machine guns in the Medium-caliber range. For this purpose, a primary coil is arranged in the weapon housing, which interacts inductively with a secondary coil in the cartridge's ignition system and transmits the ignition energy required for ignition. The ignition energy is provided by an external supply (battery, vehicle electrical system, etc.). For this, cables must be laid. DE 32 31 369 C1 is an example Secondary coil for the cartridge described.

Die FR-A-2,637,972 beschreibt ein Geradzug-Verschlußsystem für eine automatische Rohrwaffe, worin eine induktive Anzündvorrichtung integriert ist. Diese Anzündvorrichtung besteht aus einem stabförmigen Eisenkern über den konzentrisch ein ringförmiger Permanentmagnet bewegbar ist, wodurch im Eisenkern ein Stromstoß induziert wird. Dieser Stromstoß induziert bei der Anzündung in der Patrone in einer dort angebrachten Spule einen Stromstoß, der dann die Patrone anzündet. Im Waffenkörper selbst ist keine Spule angeordnet.FR-A-2,637,972 describes a straight-line locking system for an automatic Gun in which an inductive igniter is integrated. This igniter consists of a rod-shaped iron core over the concentric a ring-shaped permanent magnet is movable, whereby a in the iron core Current surge is induced. This current surge induces when ignited in the Cartridge in a coil attached there a surge of electricity, which then the cartridge Kindle. There is no coil in the weapon body itself.

Der Erfindung liegt die Aufgabe zugrunde, ein induktives Zündsystem so weiterzubilden, dass die erforderliche Zündenergie intern also ohne extra Versorgung erzeugt und bereitgestellt wird, die Betriebssicherheit verbessert ist und der Zeitpunkt der Anzündung genau einstellbar ist.The invention has for its object to develop an inductive ignition system so that the required ignition energy internally without additional supply is generated and provided, the operational safety is improved and the timing the ignition is precisely adjustable.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst. According to the invention, this object is achieved by the features of claim 1.

Die erfindungsgemäße Lösung zeichnet sich dadurch aus, dass erfindungsgemäß im Waffengehäuse ein von einer Spannstellung in eine Abschussstellung verschiebbarer Waffenverschlusskörper angeordnet ist, in dem sich die Primärspule befindet und dass zur Erzeugung der Zündenergie ein induktiver Stoßgenerator vorgesehen ist, dessen Spulensystem im Waffenverschlusskörper und dessen Magnetsystem im Waffengehäuse angeordnet ist, wobei beim Verschieben des Waffenverschlusskörpers von der Spannstellung in die Abschussstellung das Spulensystem am Magnetsystem vorbeigleitet und im Spulensystem die erforderliche Zündenergie induziert.The solution according to the invention is characterized in that according to the invention in the weapon case from a cocked position to a firing position Slidable weapon breech body is arranged, in which the primary coil is located and that an inductive pulse generator for generating the ignition energy is provided, the coil system in the weapon breech body and whose magnet system is arranged in the weapon housing, while moving of the weapon breech body from the cocking position to the firing position the coil system slides past the magnet system and the required one in the coil system Ignition energy induced.

Erfindungsgemäß ist im Waffenverschlusskörper eine elektronische Schaltung zur Zwischenspeicherung und/oder Aufbereitung der im Spulensystem des Stoßgenerators erzeugten Zündenergie und zur zeitgerechten Weitergabe an die Primärspule vorgesehen..Zur Zwischenspeicherung wird zweckmäßigerweise ein Kondensator eingesetzt und zur Aufbereitung ein Gleichrichter. According to the invention, there is an electronic circuit in the weapon breech body for intermediate storage and / or preparation of the in the coil system of the shock generator generated ignition energy and for timely transmission to the primary coil provided..For temporary storage, a Capacitor used and a rectifier for conditioning.

Der Waffenverschlußkörper ist bevorzugt entgegen der Kraft einer Feder von der Abschußstellung in die Spannstellung verschiebbar und wird zum Spannen über einen Ladehebel verschoben.The weapon breech body is preferably against the force of a spring from the The firing position can be moved into the cocking position and is used for cocking Loading lever moved.

Die erfindungsgemäße Lösung der Aufgabe ist durch folgende Merkmale gekennzeichnet:

  • a) Die Erzeugung der Zündenergie erfolgt durch einen induktiven Stoßgenerator. Ein Spulensystem erfährt durch ein "Vorbeifahren" an Permanentmagneten eine Durchflutung von wechselnden Magnetfeldern, wobei eine Induktionsspannung an den Klemmen des Spulensystems abgegriffen wird.
  • b) Die notwendige Bewegung zur Generierung der Induktionsspannung wird durch die interne Waffenkinematik (Relativbewegung des Waffenverschlußkörpers zum feststehenden Gehäuse) erreicht.
  • c) Die Zwischenspeicherung der Energie zur Zündung der Patrone erfolgt in einem Energiekreis (Kondensator) und wird zum Zweck der Zündung der Patrone durch eine geeignete, nicht näher beschriebene Elektronik über ein induktives Übertragungssystem (Primärspule im Waffenverschlußkörper, Sekundärspule in der Patrone) in den induktiven Anzünder der Patrone eingekoppelt. Die Zündung der Patrone wird eingeleitet.
    • The achievement of the object according to the invention is characterized by the following features:
  • a) The ignition energy is generated by an inductive shock generator. A "passing" past permanent magnets causes a coil system to be flooded with changing magnetic fields, an induction voltage being tapped at the terminals of the coil system.
  • b) The necessary movement to generate the induction voltage is achieved by the internal weapon kinematics (relative movement of the weapon breech body to the fixed housing).
  • c) The intermediate storage of the energy for igniting the cartridge takes place in an energy circuit (capacitor) and is used for the purpose of igniting the cartridge by suitable, unspecified electronics via an inductive transmission system (primary coil in the weapon breech body, secondary coil in the cartridge) in the inductive Cartridge lighter coupled. The cartridge is started.

    • Besondere Merkmale sind:

    • Der induktive Stoßgenerator ist Bestandteil des feststehenden Waffengehäuses sowie des beweglichen Waffenverschlußkörpers.
    • Die Zündenergiespeicherung bzw. Zwischenspeicherung im Kondensator und der funktionsgerechte Energietransfer in die Patrone über eine geeignete Steuerelektronik ist im beweglichen Waffenverschlußkörper integriert.
    Special features are:
    • The inductive shock generator is part of the fixed weapon housing and the movable weapon breech body.
    • The ignition energy storage or intermediate storage in the capacitor and the functional energy transfer into the cartridge via suitable control electronics are integrated in the movable weapon breech body.

    Die Erfindung hat daher folgende Vorteile:

    • Externe Energieversorgung entfällt.
    • Bedingt durch den Funktionsablauf in der Waffe ist keine zusätzliche Sicherheitseinrichtung für die Funktionselektronik gegen unbeabsichtigte Schußauslösung notwendig.
    • Elektrische Verbindungen zwischen Energiegenerierung, Energiespeicher und Induktionskreis sind unkritisch.
    • Sämtliche elektrischen Funktionskomponenten sind integraler Bestandteil des Waffenverschlußkörpers, eine problemlose schnelle Austauschbarkeit durch ein Ersatzteil (Waffenverschlußkörper) ist gegeben.
    Im Waffenverschlußkörper (beweglich) - nachfolgend auch Verschluß genannt - befinden sich die Primärspule, eine nicht näher bezeichnete Steuerelektronik, die die im Kondensator gespeicherte Energie (erzeugt mittels induktivem Stoßgenerator) auf die Primärspule dann freigibt, wenn sich die Patrone im Patronenlager befindet und der Verschluß sicher geschlossen ist (Eventuell erfolgt vorher eine Abfrage über einen Sensor oder es ist eine elektronische Zeitverzögerung vorgesehen. Es muß sichergestellt sein, daß der Verschluß auch wirklich zu ist.). Der Stoßgenerator ist "quasi" zweigeteilt.The invention therefore has the following advantages:
    • There is no external energy supply.
    • Due to the functional sequence in the weapon, no additional safety device for the functional electronics against unintentional firing of a shot is necessary.
    • Electrical connections between energy generation, energy storage and induction circuit are not critical.
    • All electrical functional components are an integral part of the weapon breech body, there is a problem-free quick interchangeability with a spare part (weapon breech body).
    The weapon breech body (movable) - hereinafter also called the breech - contains the primary coil , an unspecified control electronics , which releases the energy stored in the capacitor (generated by means of an inductive shock generator ) onto the primary coil when the cartridge is in the chamber and the breech is securely closed (a query may be made beforehand via a sensor or an electronic time delay is provided. It must be ensured that the lock is really closed.). The shock generator is "quasi" divided into two.

    Im Waffenverschlußkörper befinden sich Spulen, über ein weichmagnetisches Joch gewickelt. Permanentmagnete befinden sich im feststehenden Waffengehäuse. Die beiden Teile sind so angeordnet, daß, wenn aufgrund des "Schußbefehts" der Waffenverschlußkörper von der Spannstellung in Abschußstellung fährt (während dieses Vorgangs wird gleichzeitig die Patrone ins Patronenlager geschoben), das weichmagnetische Joch und die Magnete in Deckung kommen, wodurch im weichmagnetischen Joch eine Magnetflußänderung erfolgt, die eine Spannung in den Spulen induziert. Dieser Spannungsimpuls (eine gedämpfte Schwingung), wird über eine Gleichrichterschaltung dem Kondensator zugeführt und lädt diesen auf. Die im Kondensator gespeicherte Energie wird zum Zwecke der Zündung über einen elektronischen Schalter auf die Primärspule entladen. Hierbei entsteht wiederum ein wechselndes Magnetfeld, welches in den induktiven Anzünder der Patrone eingekoppelt wird; der Zündvorgang der Patrone wird eingeleitet. Der Waffenverschlußkörper fährt wieder zurück. Der Vorgang beginnt von Neuem (z. B. bei Dauerfeuer oder Feuerstoß).There are coils in the weapon breech body, via a soft magnetic yoke wound. Permanent magnets are located in the fixed weapon housing. The both parts are arranged so that when due to the "shooting command" Gun lock body moves from the cocking position to the firing position (while this process, the cartridge is pushed into the chamber at the same time) soft magnetic yoke and the magnets come into congruence, which in the soft magnetic yoke a change in magnetic flux occurs which creates a voltage in the Coils induced. This voltage pulse (a damped oscillation) is over a rectifier circuit is supplied to the capacitor and charges it. The in The energy stored in the capacitor is used for ignition purposes Discharge electronic switch on the primary coil. This in turn creates a changing magnetic field, which is in the inductive igniter of the cartridge is coupled; the cartridge fires. The Gun breech body moves back again. The process starts again (e.g. in case of continuous fire or burst of fire).

    Soll die Waffe zur ersten Schußabgabe aktiviert werden, muß der Waffenverschlußkörper mit Hilfe einer geeigneten Einrichtung (z. B. Ladehebel) in Ausgangsposition gebracht werden (er befindet sich dann in Spannstellung). Soll ein Schuß abgefeuert werden, wird der Waffenverschlußkörper über den Abzug und eine entsprechende Mechanik nach vorne bewegt, der Funktionsablauf ist entsprechend dem beschriebenen Vorgang.If the weapon is to be activated for the first shot, the Gun lock body with the help of a suitable device (e.g. loading lever) in Be brought to the starting position (it is then in the clamping position). Should a The weapon breech body is fired over the trigger and a shot appropriate mechanics moved forward, the functional sequence is corresponding the process described.

Angrenzend an den Waffenverschlußkörper 5 befindet sich ein Waffenrohr 13 in dem gerade eine Patrone 4 eingeführt ist. Die Patronenzuführung ist nicht gezeigt.Fig. 1 shows schematically the operation of an inductive ignition system for Infantry weapons. In a weapon housing 1 is a slidable weapon breech body 5, also simply called a closure. Adjacent to the weapon breech body 5 there is a weapon barrel 13 in which a cartridge 4 is currently in place is introduced. The cartridge feeder is not shown.

    Im Waffenverschlußkörper 5 ist ein Spulensystem 7 angeordnet, welches zusammen mit einem im Waffengehäuse 1 angeordneten Magnetsystem einen Stoßgenerator 6 bildet. Außerdem befindet sich im Waffenverschlußkörper 5 eine elektronische Schaltung 9 mit beispielhaft einem Gleichrichter 14, einem Kondensator 15 und einem elektronischen Schalter 16. An dem der Patrone 4 zugewandten Ende ist eine Primärspule 2 angeordnet, die bei der Anzündung Energie auf eine in der Patrone 4 angeordnete Sekundärspule 3 überträgt.In the weapon breech body 5, a coil system 7 is arranged, which together a shock generator 6 with a magnet system arranged in the weapon housing 1 forms.

At the end facing the cartridge 4 is an Primary coil 2 arranged, the energy to a in the cartridge 4th arranged secondary coil 3 transmits.

    Wird die Waffe geladen, dann wird mit dem Ladehebel 11 (nur schematisch angedeutet) der Waffenverschlußkörper 5 gegen die Kraft einer Feder 10 in eine Spannstellung gebracht. Diese Spannstellung ist gestrichelt eingezeichnet. Die Feder 10 ist gespannt und will den Waffenverschlußkörper in die Abschußstellung (vorher beschrieben) zurückdrücken. Beim Schuß wird ein Trigger 12 (Abschußhebel etc.) betätigt und der Waffenverschlußkörper 5 bewegt sich von der Spannstellung in die Abschußstellung. Dabei gleitet das Spulensystem 7 im Waffenverschlußkörper 5 am Magnetsystem 8 im Waffengehäuse 1 vorbei. Hierbei wird eine Zündspannung im Spulensystem 7 erzeugt und an eine elektronische Schaltung 9 geleitet. Die Verbindungsdrähte oder Leiterbahnen sind nicht gezeigt. Diese elektronische Schaltung 9 enthält zumindest einen Kondensator 15, einen Gleichrichter 14 und einen elektronischen Schalter 16. Außerdem sollte noch ein Zeitglied bzw. eine Verzögerungsschaltung enthalten sein, die erst wenn sich der Waffenverschtußkörper 5 in Abschußstellung befindet, die Zündspannung an die Primärspule 2 anlegt. Vorher muß sichergestellt sein, daß sich der Waffenverschlußkörper 5 auch wirklich in der Abschußstellung befindet. Dies könnte z. B. über ein Sensorelement geschehen.If the weapon is loaded, then the loading lever 11 (only schematically indicated) the weapon breech body 5 against the force of a spring 10 in a Brought tension position. This clamping position is shown in dashed lines. The feather 10 is cocked and wants the weapon breech body in the firing position (before described). When firing a trigger 12 (launch lever etc.) actuated and the weapon breech body 5 moves from the cocked position in the Firing position. The coil system 7 slides in the weapon breech body 5 on Magnet system 8 in the gun housing 1 over. Here, an ignition voltage in the Coil system 7 generated and passed to an electronic circuit 9. The Connecting wires or conductor tracks are not shown. This electronic Circuit 9 contains at least one capacitor 15, a rectifier 14 and an electronic switch 16. In addition, a timer or Delay circuit included, which is only when the weapon breech body 5 is in the firing position, the ignition voltage is applied to the primary coil 2. Before must be ensured that the weapon breech 5 really in the Firing position. This could e.g. B. happen via a sensor element.

    Liegt die Zündspannung an der Primärspule 2 an, wird in der Sekundärspule 3 in der Patrone 4 eine Spannung induziert, die zu einer Anzündung der Patrone 4 führt.Is the ignition voltage at the primary coil 2, in the secondary coil 3 in the Cartridge 4 induces a voltage that leads to ignition of the cartridge 4.
